Uhh... reality check?
Lester's is a mighty fine pitcher, but greatness?
Why not copy Zumaya or Wagner, they throw high 90's?
Don't bother with Maddux, he throws so slow IMO.
Pitching mechanics are not neccesarily about copying your idol EVEN IF they have the most amazingly efficient, simple, dynamic mechanics that a chimpanzee ever layed eyes on, it's about what you as an individual who is in no way related to your idol to find what's comfortable for you. From there, you can make adjustments and to get better.
Just do what you're cool and comfortable with. If you find that replicating Lester's mechanics work for you, go ahead. Just do what you gotta do.
